Parameter Description
Group Mode Dynamic grouping has two modes: Enabled and Disabled. When the
grouping is Disabled, no dynamic grouping occurs. Each controller
optimizes the parameters of only those access points that are associated
with the controller. When grouping is Enabled, the controller forms
groups and elects a leader to perform better dynamic parameter
optimization.
Group Update Interval When grouping is on, this interval (in seconds) represents the period
with which the grouping algorithm is run by the Group Leader.
Grouping algorithm also runs when the group contents changes and the
automatic grouping is enabled. A dynamic grouping can be started upon
request from the system administrator. Default value is 3600 seconds.
Group Leader This is the MAC address of the group leader for the group containing
this controller.
Is this Controller Group
Leader
Yes this controller is the group leader or No the controller is not the
group leader.
Last Group Update The elapsed time since the last group update in seconds. This is only
valid if this controller is a group leader.
